Detailed Description

Example 1:

the fermented Pu' er tea is prepared by adopting a special fermentation process which is developed in the course of the subject group in the past, namely a Chinese invention patent (ZL 201810260681.3) technology:

one) fermentation of Pu' er tea:

1) Picking fresh leaves: manually picking two leaves or three leaves of a bud of Pu' er sun-dried green raw tea in 3-4 months in spring; the Pu' er crude sun-cured tea is a crude sun-cured tea of early-spring ancient trees of large leaf species in Menghai county, xishuangbanna, yunnan;

2) Spreading and airing: spreading the picked Pu' er tea green-dried raw tea and airing the tea in a place without direct sunlight and ventilation, and keeping the tea for 2 to 3 hours;

3) Primary selection: selecting out non-tea impurities, and selecting out fresh leaves with overlarge leaves and uneven colors to obtain high-quality Pu' er green-drying raw tea with uniform colors and sizes;

4) Fermentation: the fermentation sequentially comprises the following three links: carrying out mild fermentation, shaping mature fermentation and odor removal fermentation;

the mild fermentation takes 60 days in total, and the specific steps are as follows: the Pu' er green-sunning raw tea is stacked on the fermentation platform, the stacking height is 48-52 cm, the edge of the stacked green-sunning raw tea is trapezoidal, the air permeability of the tea pile can be ensured, the raw tea can be fully contacted with air, oxygen supply of beneficial flora in tea is facilitated, fermentation is facilitated, and substances in the tea are converted.

Uniformly spraying fermentation liquor to the tea pile for pile fermentation, wherein the mass ratio of the Pu' er sun-dried green raw tea to the fermentation liquor is 10:3, controlling the temperature on the fermentation platform to be not more than 60 ℃, turning over once every 7 days, stopping fermentation when the fermentation is completed by three times, and drying the tea blocks to form brick red granular tea blocks with the water content of 10-15%; in the process of spraying the fermentation liquor, the tea pile needs to be sprayed from the middle to the periphery in a diffused mode, so that the beneficial bacterium groups for fermentation are activated synchronously, the mass ratio of the raw tea to the fermentation liquor is controlled, and the most appropriate active environmental humidity of the beneficial bacterium groups is provided. The fermentation broth is preheated to 30 ℃ before spraying, which is to ensure optimal activity of beneficial bacteria.

The specific steps of the shaping mature fermentation are as follows: piling the slightly fermented tea blocks on a fermentation platform for re-fermentation, controlling the temperature on the fermentation platform to be 50-55 ℃, fermenting for 90 days, turning over once every 7 days, and spraying fermentation liquor, wherein the spraying amount of the fermentation liquor each time is 5-10% of the total weight of the tea blocks; after fermentation is finished, tea blocks with brick red inner cores and black surfaces are obtained, and the maturity of the tea blocks is seven-fold; the fermentation platform is formed by pouring cement and clay, the concrete is prepared from the cement, the clay and fine sand according to the mass ratio of 1. Two closable ventilation openings are further formed in the bottom of the platform body. The Pu' er green-sun raw tea or tea blocks are stacked on a fermentation platform, and a clean net-shaped support with the aperture of less than 3mm is placed on the upper part of a ventilating bottom plate of the fermentation platform in advance.

The fermentation liquor is white sand well water from Xishuangbanna Meng Hai county, a well is drilled in an area with a white sand layer to reach the white sand layer, and the well water is extracted to serve as the fermentation liquor. After volcanic eruption, the white sand well water vibrates and dissolves various trace elements in geology into water to form magnetized water rich in mineral substances. The well water can be extracted in a region with a sandstone layer, the best of Meng Hai county of Yunnan province is obtained, and substances contained in the well water are beneficial to the activity of beneficial flora in tea fermentation, so that the tea of a fermented finished product has fine waterway, mellow taste and lasting soup, and plays a positive role in promoting the later-stage conversion of the tea.

The total 160 days for deodorizing and fermenting are as follows: carrying out low-temperature and low-humidity fermentation on the twice fermented tea blocks until the tea blocks have no foreign flavor, wherein the fermentation temperature is 45-50 ℃, and the humidity is 50%;

in the process of deodorizing fermentation, besides spraying fermentation liquor on the surface of tea blocks, spraying deodorizing spray on the surface of the tea blocks uniformly, wherein the amount of the deodorizing spray is 1/10-1/8 (volume) of the fermentation liquor amount required in the process of deodorizing fermentation, and the preparation method of the deodorizing spray comprises the following steps: selecting crisp apples with green tangerine peels, removing kernels, squeezing into fresh fruit juice, and uniformly mixing the fresh fruit juice of the apples and purified water according to a volume ratio of 1.

Spraying the peculiar smell removing spray every other 24 hours after spraying the fermentation liquor.

The green-skin crisp apple contains a large amount of apple polyphenol, and the apple polyphenol contains chlorogenic acid, catechin, epicatechin, apple condensed tannin, phlorizin, phloretin, anthocyanin and the like. Apple polyphenol mainly has the effects of resisting oxidation, deodorizing, preventing vitamin loss and the like.
